This is for security reasons as well as putting less reliance on identity servers. +However, currently Synapse only supports sending emails, and does not have support for +phone-based password reset or account registration. If Synapse is configured to handle these on +its own, phone-based password resets and registration will be disabled. For Synapse to send +emails, the ``email`` block of the config must be filled out. If not, then password resets and +registration via email will be disabled entirely. + +This release also deprecates the ``email.trust_identity_server_for_password_resets`` option and +replaces it with the ``account_threepid_delegates`` dictionary. This option defines whether the +homeserver should delegate an external server (typically an `identity server +<https://matrix.org/docs/spec/identity_service/r0.2.1>`_) to handle sending password reset or +registration messages via email and SMS. + +If ``email.trust_identity_server_for_password_resets`` is set to ``true``, and +``account_threepid_delegates.email`` is not set, then the first entry in +``trusted_third_party_id_servers`` will be used as the account threepid delegate for email. +This is to ensure compatibility with existing Synapse installs that set up external server +handling for these tasks before v1.4.0. If ``email.trust_identity_server_for_password_resets`` +is ``true`` and no trusted identity server domains are configured, Synapse will throw an error. + +If ``email.trust_identity_server_for_password_resets`` is ``false`` or absent and a threepid +type in ``account_threepid_delegates`` is not set to a domain, then Synapse will attempt to +send password reset and registration messages for that type. + +Email templates +--------------- + +If you have configured a custom template directory with the ``email.template_dir`` option, be +aware that there are new templates regarding registration. ``registration.html`` and +``registration.txt`` have been added and contain the content that is sent to a client upon +registering via an email address. + +``registration_success.html`` and ``registration_failure.html`` are also new HTML templates +that will be shown to the user when they click the link in their registration emai , either +showing them a success or failure page (assuming a redirect URL is not configured). + +Synapse will expect these files to exist inside the configured template directory.
